I love the Moorer one....just because of the way it happened, when it happened and the fact that George was losing that fight. The ref said it was the hardest punch he has ever heard live. It split the top of Moorer's mouth WIDE OPEN.....makes me shudder when I think of it.
Joe Frazier, the first one (I think it was the first one). That's where Joe was doing some "hop-and-skip" routine after Foreman clocked him. Foreman's fights against Frazier might have been the best displays of Foreman's pure power, to take such a tough guy as Joe and just destroy him.
